Messi's opener was cancelled out by a Kevin Gameiro equaliser, but the result gave PSG an unassailable four-point lead over second-placed Lens with one match of the season remaining.
PSG moved ahead of the previous record of 10 titles set by Saint-Etienne in 1981 and which they equalled a year ago under former coach Mauricio Pochettino.
It is PSG's ninth title in the last 11 seasons, a period in which they have dominated French football under Qatari ownership.
"This afternoon I watched the last day of the season in the Bundesliga and you can see that it is very difficult to win the league, any league," PSG coach Christophe Galtier told broadcaster Canal Plus.

"The reigning champions in all European leagues have often had problems this season, so we appreciate what this means.
"It is a title and we must not believe it is normal to win, even if we are Paris Saint-Germain."
PSG started the penultimate weekend of the season six points clear of nearest rivals Lens with just six points to play for, and with a far better goal difference.
A Lens slip-up would have seen the capital side crowned champions with a game to spare even in defeat, but in the end they needed the draw as their challengers eased to a 3-0 win over already-relegated Ajaccio.
Kylian Mbappe set up Messi to put PSG ahead just before the hour with his 16th Ligue 1 goal this season.
Ex-Paris striker Gameiro equalised with 11 minutes left, bundling in the rebound after Gianluigi Donnarumma had saved from Morgan Sanson.

The draw ultimately suited both teams as it enabled Strasbourg to guarantee their top-flight survival.
PSG started the season superbly and did not lose a game in any competition before the World Cup.
However, they lost six of their first 17 league games in 2023 and were eliminated from the Champions League in the last 16 by Bayern Munich and in the French Cup at the same stage.
Those results increased speculation that Galtier -- who also won the title with Lille two years ago -- will be replaced in the close season.

With PSG out of the Champions League and only four Ligue 1 matches remaining as they target a record 11th title, this is likely to be Messi's penultimate appearance at the Parc des Princes.
The Argentinian netted two finishes, including a superb bicycle kick, after goals from Neymar, Achraf Hakimi and Marquinhos got the champions off to a dominant start at Stade Gabriel-Montpied.
This is what actually happened, after one of the people who obtained the precious treasure, the used tissue, after the conference placed an advertisement on one of the popular sites announcing the offer to sell the tissue paper that Messi used for one million dollars.
Di Maria said, "Messi's situation is not ideal now, it is not easy for him to stay in a hotel with his family, people are used to respecting the privacy of players, but with Leo we can no longer move much, there are always cars and motorcycles nearby to protect the team."
